PI-IONOGRAPH.

Specification of Letters Patent.

Patented oct. .-5, 1909.

' o ull whom it may concern:

Be it known that I. HERMAN XVOLKE, a citizen of the United States, and a resident oi.' Orange. in thc county ot' Essex and State of New Jersey, have invented cert-.1in new and useful Improvements in Phonographs, otl which the following is a description.

Bly invention relates to phonographs, and has for its object the lprovision of 'means whereby the traveling carriage which carries the. reproducerior recorder, may be fed at either of two desired rates of speed, so as to adapt it to operate, for example, upon records having respectively-one hundred and vtwo hundred threadsv per inch, and said means are preferably designed so that they may be readily applied to phonographs of ordinary construction, such as are now in general use throughout this and other countries.

In order that the invention may be more fully understood, reference is hereby made to the accompanying drawing of which- Figure 1 isa section on linel-jl ot' Fig. 2, viewed in the direction indicated by the arrow; Fig. 2 is a section online 2 2- of Fig. 1 showing my invention applied to a phonograph of well-knownI form; Fig. 3 is a detail View of the gears forfeeding the traveling carriage' as Viewedin a direction at right angles to Fig. 2, and Fig. 4 is a sec- -vtional detail of the -worm gear and adjacent -suc-h as 100 threads to the inch.

. in the usual manner.

parts.

The phonograph shown is of ordinary form and comprises a base or body 1 which supports the main shaft 2 formed with a feet, screw 3. which is generally of tine pitch, The body 1 also carries theback rod 4. upon which the sound box carriage 5 is slidably mounted There is an 'arm G which is removably applied to theback .rod 4, being held by a clamping screw 7. A screw 8 is threaded in said `arm so thatits lower end rests upon the body 1 and aords an angular adjust-ment with respect to the back rod 4. `A frame 9 is pivoted at 10 to the arm 6 and said frame is formed with a bearing 11 in which is journ'aled a shaft 12, to which a Worin gear-13 isseeured bythe set screw 14, said worm gear meshing with the thread of the feed screw 3, and being held in yielding engagementy therewith by the action of a spring 15 which secured to theend of the arm 6 by the. screw 16, and

i presses against a pin orabutment 17 secured to the' frame 9. l. y

There is an auxiliary frame composed of two plates 18 and 19, which are secured together by screws 20 threaded in posts 21 which are rigid with the plate 18, and againstthe ends of which the plate 19 is clamped by the said serci s. The plate 18 oscillates upon the shaft 12 between the bearing 11 and a spur gear 22 which is secured tothe end of the shaft 12 by afscrew 23. The plate 1S' is provided with a pair of pins or studs 24 and 25. Upon the pin 25 and secured by the screw 2G is rotatably mounted a' spur gear 2T meshing with the gear 22, and` upon they pin 24 and secured by the screw 28 is a pair of spur gears 29 and 30 secured together, the gear 29 meshing withk the gear 22. The gears 22, 27 and 29 are preferably all of the same diameter and the gear 30 twice the diameter of said gears. l

. Means are provided for oscillating the plate 1S, and as shown comprises a. sleeve 31 rotatably mounted on a pin 32 which is threaded in the frame 9. One end ot' said sleeve is provided with a milled head 33 and the opposite end is cut away to form a pair of shoulders 34 and 35 which are adapted to abut against a pin 36 carried by a plate 37 secured to the frame 9, in order to limit the angular movement of the sleeve 31 in either direction. A cam surface or eccentric 88 is formed upon the sleeve 31,'near its lower end, the same being situated between the arms of ay yoke 39 which is secured-to the plate 18 by screws 40. 'This eccentric bears against the arms of said yoke as the sleeve 31 is oscillated upon the piu 32 and thereby causes-oscillation of the platt` 1S upon its axis, which brings the gears 27 and 3() respectively into and out of engagement with a rack 41, which is secured to an arm 42, and which is in turn secured yto the sound box carriage 5 by screws 43. This rack has a cutaway portion near one end thereof of suficient extent to effect a' disengagement of the gear 27 with the'rack when that point is reached, but which does not -effect the engagement of the gear 30, owing to itsf'greater. diameter. Indicating figures 44 are preferably applied to the opposite sides ot the sound box carriage.

The operation of the deviceis as tollows: Then the parts -are iu the positions shown 1n sleeve 31 to designate the rate of feed ot the revolution thereof, Corone one-hundredth ofi an inch. 'The indicia 44, Whichy are visible et; this time are the figures 100, which means` i@ .thatthe rate of feed of tlie sound bor: car

, riage issuitable for `'operati-tig upon records v having one hundred threads per incli.v When the sleeve 3'1- is rotated thr'ough an angleof 180 the figures 200 (not shown) will come into view, and at' the Sametime the plate 1B willbe oscillated'to 'such an extent as to re` move the gear from engagement with' the' racl 41, and. to bring into engagement withl vsaid rack the gear 27, which gear is driven 2U.l by the gearQQ by-reasoirof the engnigement l of the worm wheel 13 with the feed screw 3. l In this position of the parts, the sound box carriage will be driven at, a slower rate of speed than before and preferably ata rate 25 which is equal' to one half 'the pitch of the feed screw for each revolution thereof, so as to adapt the sound b ox carriageto operate ilpon the records having two hundred threads to the inch, as indicated by the .fig- 30 ures upon the sleeve 31. rIt is obvious that all that. is necessary to do, Ain order to change then-atc of feed of the sound box carriage is to rotate the sleeve. 3l thioughan angle-of 180, so as to oscillate the plate'18,'wliich movement does not aect in any Way-tbe po-A sitionof the frame 9 or the worin Wheel 13. The ,length 'and position 'of the rack 41 is such and the cut-away portion is so situated that no matter whether the gear 27 or 40 the gear 30 is feeding the carriage the rack the end of (he record surface. Having now described my invention,
